Because that's what worked for me to reproduce his commands.

He didn't have to. His point was merely that with the old ls, you can
have inherently ambiguous situations.  Think of it as an exercise for
the reader to figure out ways to get into those ambiguous situations.

Knowing the pitfalls makes it easier to justify why an output that is
unambiguous was chosen as the new default over the previous ambiguous
output; any further changes to the default are now a matter of
fine-tuning about how much (or how little) decoration we can get away
with, while still avoiding a regression to the situation of ambiguous
output.
